The Seaflo 43 Series is a compact, self-priming 12V DC diaphragm pump designed for marine, RV, and off-grid water systems, delivering up to 3.0 GPM at 55 PSI. It features internal bypass technology and Variable Flow Technology to minimize cycling and noise while eliminating the need for an external accumulator tank. It is ideal for medium-duty, battery-powered water systems in RVs and boats requiring consistent pressure for multiple outlets.

The Amarine Made AC 110V Self Priming Water Pressure Pump is a compact diaphragm pump designed for high-pressure fresh water washdown in RVs and boats. It features a built-in pressure switch and thermal protection, making it safe and easy to use. However, the lack of detailed material specifications and connection sizes limits its appeal for complex installations.
